There are dozend Situations in which Backtrack 3 comes in handy.
\nBacktrack 3 is an special Linux Suite of Security Auditing Tools which allow i.e. WEP Cracking, Network Security Checking, Sniffing, and so on.
\nTo make this nice Suite a bit more portable, we will put it onto an Usb Stick and customize it with Eee901 Drivers, persistent Changes and Nessus 4!<\/p>\n
Download:<\/strong> Preparation:<\/strong> mount \/dev\/sda2 \/mnt 5) Done, boot to Windows<\/p>\n Installation of Backtrack 3:<\/strong> label eee901save label eee901 WARNING! changes=\/dev\/sda2 MUST be changed to what you saw on the partition - and maybe you still need to try it out. Save after you're done<\/p>\n 7) Open cmd and access your usb stick, cd to boot\\syslinux\\ and execute this: 8) You're done. Boot from the stick, it should work.<\/p>\n Insallation of Nessus 4:<\/strong> Install NessusServer Follow the install instructions<\/p>\n \/opt\/nessus\/sbin\/nessus-mkcert Launch the Server: Install NessusClient Launch the Client: Nessus Install taken from: http:\/\/forums.remote-exploit.org\/backtrack3-howtos\/22031-backtrack3-nessus-4-0-install.html
\nBacktrack 3 USB Version: http:\/\/www.remote-exploit.org\/backtrack_download.html
\nunetbootin Windows: http:\/\/unetbootin.sourceforge.net
\nPartiton Tool, like partedmagic: http:\/\/partedmagic.com
\nEee901 Pack: 901_net_gfx.lzm (you'll find it in google)
\nNessus 4.0.2: http:\/\/www.nessus.org\/download\/
\n( We need the 4.0.2 as Nessus-4.0.2-linux-generic32.tar.gz and the Graphical Linux Interface for nessusd NessusClient-4.0.2-es4.i386.rpm )
\nAnd you should help yourself to an free personal key under http:\/\/www.nessus.org\/plugins\/?view=register-info<\/p>\n
\nFirst thing is you need to prepare the Usb Stick. For Backtrack 3, an 2 GB Stick should be ok. For Backtrack 4, you would need an 4 GB Stick at least.
\n1) Get your stick and partedmagic CD
\n2) Plug it in and boot to partedmagic
\n3) Create with the Partitioneditor 2 Partitions
\n- 1) fat32, 900mb
\n- 2) ext2, 1100mb
\n-> write down if your usb stick is sda1, sdb1, or what.
\n4) Reboot - again to partedmagic
\nNow create an folder called changes to the second partition.
\nShould look somehow like this (not nice, but should work if you're on sda2...):<\/p>\n
\ncd \/mnt
\nmkdir changes
\ncd \/
\numount \/mnt<\/p>\n
\n1) Start unetbootin
\n2) Choose Disk Image, ISO and as file the Backtrack3 USB
\n3) Check wheter the destination drive is correct (your usb stick, fat32 partition) - CHECK TWICE! And Error would kill your System!
\n4) Press Ok and wait until its done, do NOT reboot
\n5) Copy 901_net_gfx.lzm to your usb stick, folder BT3\\optional
\n6) Open syslinux.cfg in boot\\syslinux\\ and add following lines, which will be your new menu entrys for booting from the usb stick - with eee901 drivers. <\/p>\n
\nmenu label BT3 Graphics mode (Eee901) - Save Changes
\nkernel \/boot\/vmlinuz
\nappend vga=785 initrd=\/boot\/initrd.gz ramdisk_size=6666 root=\/dev\/ram0 rw load=901_net_gfx autoexec=kdm changes=\/dev\/sda2<\/p>\n
\nmenu label BT3 Graphics mode (Eee901)
\nkernel \/boot\/vmlinuz
\nappend vga=785 initrd=\/boot\/initrd.gz ramdisk_size=6666 root=\/dev\/ram0 rw load=901_net_gfx autoexec=kdm<\/p>\n
\n2 means second partiton and thats right - ext2 partition. This changes tells Backtrack where it should save the changes you make while working in it.
\nthe changes could be sda2 or sdb2 or sdc2. But mostly its sda2.<\/p>\n
\nsyslinux.exe -ma -d \\boot\\syslinux H: (H: should be your usb drive letter... will be different!)
\nThis will write the bootmanager to the usb stick with the settings you entered in 6).
\nAfter changing for example the changes line there, you will need to repeat this again, also.<\/p>\n
\nNessus is an auditing tool which is really strong - but is not complete opensource - so you need to install it manually.
\nBoot onto your Backtrack 3...<\/p>\n
